Valve cover oil leaks are a well-known failure point on BMW S55 engines, especially as mileage increases. The OEM plastic valve cover is exposed to constant heat and pressure, which can lead to warping, cracking, and oil seepage over time. This Bremmen aluminum valve cover kit offers a durable, performance-focused upgrade designed to eliminate these common issues. Constructed from high-quality aluminum and equipped with an integrated PCV system, it delivers improved strength, heat resistance, and long-term reliability. This direct-replacement kit includes the aluminum valve cover (11127850244) and crankcase ventilation hose (11367609963), providing a complete solution to restore proper sealing and engine performance.

Includes gaskets, sealing washers, and CCV hose for an all-inclusive service.

This axle-back exhaust system is manufactured entirely from titanium. This makes this system ideal for cutting weight while being structurally stronger than the OE exhaust system. The engineers at Akrapovic have retained the dual mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car. The included exhaust pipe tips are made completely from titanium OR a carbon fiber/titanium composite to add a high-end, refined style. Performance has not been left out of the design. The system dramatically reduces backpressure and is an excellent starting point for further engine tuning or turbo modifications. Even when installed on an otherwise stock vehicle a gain of 7.3 horsepower and 17.4 Nm/12.8 lbs-ft of torque are achieved. Furthermore, a weight reduction of 3.0 kg/6.6 lbs. is realized. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered. Titanium muffler with integrated exhaust valves Statistics: +7.3 HP (at 4400 rpm) +17.4 Nm/12.8 lbs-ft of torque (at 2350 rpm) 3 kg/6.6 lbs. lighter than stock Not for sale outside the US or Canada.

The Sound Kit is a remote control for the valves on the Akrapovic muffler. While the muffler valves are also controlled like the factory valves in Comfort, Sport, and Sport+ modes, the Sound Kit will let you open or close the valves via handheld remote or even from your phone (iOS or Android app). The Sound Kit works with the existing wiring for the Akrapovic system so installation is a breeze.
